... efficiency in inclined well. A detailed sensitivity analysis of the effect of gas and liquid flowing rates, drilling rate, foam rheological properties, borehole geometry, wellbore inclination and the rate of gas and liquid influx from the reservoir on the cutting transport efficiency in inclined wells...

... characteristics (n, K), drilling rates, wellbore geometry and drillpipe eccentricity. The results of the sensitivity analysis showing the effects of various drilling operational parameters on the efficiency of solids transport are presented. The model developed in this study can be used to develop computer...

.... In this paper, a different approach is introduced in assessing drilling performance. The new approach suggests a comparison of drilling performance with respect to what is called 'technical limit of drilling rate', a maximum achievable drilling rate without risking drilling safety. Introduction The rate...
